Which of the following statements is NOT true about the $\alpha$-halogenation of carbonyl compounds?

A

$\alpha$ halogenation reaction occurs in basic conditions only.

B

The reaction cannot be stopped at the ​mono-halogenated​ state and further undergoes halogenation to give polyhalogenated products.

C

The reaction intermediate is a very reactive enolate.

D

Polyhalogenation of a methyl ketone (RCO-$CH_3$) is a typical laboratory method to identify​ the presence of methyl ketone in a given compound, and the reaction is known as a 'Haloform reaction'.
